Abz Posted September 8, 2013 Share Posted September 8, 2013 I have an RSR exhaust an I love it BUT when on long trips the drone can be quite annoying. This only happens to be between 65 - 80mph which isn't ideal for long journeys! In the past it had a bung stuck in which was great but I just can't be arsed dealing with bungs and it does sound a bit rubbish with one in. Can anyone recommend anything to cure this? Would dynamat in the boot help? Any exhaust mods I could do? It is currently double decat. Thanks in advance!! Quote Link to comment Share on other sites More sharing options...

Al Massey Posted September 8, 2013 Share Posted September 8, 2013 Exhaust butterfly's/electronic exhaust valve ^yeah as SPG said. Suprasteveo has one and it works a treat. It's on a pull lever type thing so is semi adjustable too. Quote Link to comment Share on other sites More sharing options...

Max Headroom Posted September 8, 2013 Share Posted September 8, 2013 I had an RSR on my Supe, with 2nd decat. took out rear seat and dynamatted the whole of the rear of the supe, took a couple of rolls. Worked a treat. Also helped that I am as deaf as a post. Quote Link to comment Share on other sites More sharing options...

letmeshowyou Posted September 8, 2013 Share Posted September 8, 2013 I recommend getting a Tanabe (It's beautiful how quiet mine is off boost!) Quote Link to comment Share on other sites More sharing options...
Nic Posted September 8, 2013 Share Posted September 8, 2013 Either swap it for a quieter exhaust or get a 2nd silencer welded into the mid pipe. Quote Link to comment Share on other sites More sharing options...
Alex Posted September 8, 2013 Share Posted September 8, 2013 Either swap it for a quieter exhaust or get a 2nd silencer welded into the mid pipe. Easy enough to get a 2nd baffle/expansion box fitted. Quote Link to comment Share on other sites More sharing options...

chris0132 Posted September 8, 2013 Share Posted September 8, 2013 Can't you get a bung I've got the 5zigen one and it looks pretty much the same (it said rsr on the ad when I got the car) and mine came with a bung you could have if you want Quote Link to comment Share on other sites More sharing options...
Abz Posted September 8, 2013 Author Share Posted September 8, 2013 Go 85mph Hth What do you think I have been doing?! Exhaust butterfly's/electronic exhaust valve ^yeah as SPG said. Suprasteveo has one and it works a treat. It's on a pull lever type thing so is semi adjustable too. Thinking of this route but will this have any effect on the turbo's?! Won't cause back pressure or anything like that will it? Buy a Slayer CD. Turn stereo up. I think I should mention occasionally I have my wife & little baby daughter in the car I had an RSR on my Supe, with 2nd decat. took out rear seat and dynamatted the whole of the rear of the supe, took a couple of rolls. Worked a treat. Also helped that I am as deaf as a post. Thanks Max, I might try the dynamat process just to decrease cabin noise. Here you go. That's exactly what this device does. I can bring it to JAE for you to trial. http://www.mkivsupra.net/vbb/showthread.php?284893-Apexi-spring-loaded-tail-silencer-115mm Thanks David but I'd like to avoid any bungs or anything else fitted to the end, quite like the look my exhaust just not the drone. I recommend getting a Tanabe (It's beautiful how quiet mine is off boost!) I remember hearing yours! I might have to have a better listen next week. Either swap it for a quieter exhaust or get a 2nd silencer welded into the mid pipe. Easy enough to get a 2nd baffle/expansion box fitted. Thanks guys, will look into this option. Ear plugs Certainly the cheapest solution. Certainly the cheapest Can't you get a bung I've got the 5zigen one and it looks pretty much the same (it said rsr on the ad when I got the car) and mine came with a bung you could have if you want Avoiding the bung option Chris, I have had two now... One fell out on the dual carriageway & I spent ages in the bushes looking for it and I have no idea where the other is now. It is just very fiddly & messy, and ideally want something to either quiet the drone or have a switch to flick between. Quote Link to comment Share on other sites More sharing options...

Always seem to be a few on eBay too Had a quick look and found this, the video seems pretty good! http://www.driftworks.com/qtp-electronic-exhaust-cutout-bypass-valve-and-y-pipe.html Might have a chat with Lee as his done a few of these and see what he can sort out.

Nic Posted September 8, 2013 Share Posted September 8, 2013 Thanks guys, will look into this option. Jetex UK do a good range of large bore stainless steel silencers, you'd need to check how much clearance you have underneath the car. http://www.jetex.co.uk/website/custom_parts.php?mat=Stainless&dia=3.0+inch Quote Link to comment Share on other sites More sharing options...

Looks good but I think that's more for the opposite affect, making a quite exhaust loud! I'm sure I watch a vid once of a HKS built skyline with the electronic butterfly valve and worked quite well but when looking on the website can't find it so must of stop making it. Would Lee be able to come up with anything like that do you think? Quote Link to comment Share on other sites More sharing options...

The y pipe is designed so you can have quiet and loud exhaust, but if you take off the valve, and use it in a single exhaust pipe, it will quieten it down. Suprasteveo's is awesome and I will end up getting one one of these days Quote Link to comment Share on other sites More sharing options...

Suprasteveo's is awesome and I will end up getting one one of these days The downside is that it'll add quite a big restriction, an extra silencer would quieten the exhaust without the added restriction and should cost less.

Noz Posted September 8, 2013 Share Posted September 8, 2013 I've got an exhaust control valve. Car sounds less noisey than my diesel at 60mph. It will create back pressure while closed. But that won't matter if your cruising. It's more responsive lower RPM as well. Turbo won't actually spin up with it closed. Makes me wonder if it saves fuel due to restricting fuel. You can't open a siliencer or muffler. Hodge had a ECV for sale back along not sure if he sold it though. Get a larger ECV than your pipe though. A 3" pipe should have a 4" ECV, otherwise you will create a reduction in flow. Just get a reducer either side and your sorted. Pull a lever and the noise is reduced. Open it again and its back, your can't do that with mufflers. Quote Link to comment Share on other sites More sharing options...
